Question 189857
Alpha Centauri, which lies 4.4 light years away, is the closest star system. It would be good candidate for discovering an Earth-like world. The distance to Alpha Centauri is 3,000 times farther than any space probe has ever traveled.
:
In miles, how far is the journey to Alpha Centauri?
4.4 yrs * no. of seconds in 1yr * 186,000mi
4.4 * 3600 * 24 * 365 * 186000 = 2.58(10^13) miles
:
In miles, approximately how far has the furthest space probe traveled?
{{{(2.58(10^13))/3000}}} = 8,600,000,000 miles
